micoach is all you need to get the results you want.
I'am 5 45, 160lbs. I usually wear slim-fit medium shirts and pants from both adidas performance, and originals. If you want a slim-fit/muscle-fit, buy a small size, which is what I did and still comfortable. But if you want some more room and does not care about the shape of your body, but a medium.
I have bought these shorts because I love the Adidas Response range. They are a good quality short, fit great and a very comfortable. Great for running, gym, lounging around in the sun or tale on holiday. Hope there are more colours. Find the men's range of running gear can be quite boring. But love these shorts. Will be getting the black ones.
I have just bought 2 pairs of these shorts, the others are the black ones and they are a really comfortable, lightweight short for running in. I would not hesitate to buy other pairs in different colours if they were available
I've used mine for a while now and its pretty good. Material quality is very good, no itching or rubbing so far. I am 5.8" and size small fit is decent, but I wish it to be just a bit shorter in sleeve and hem length.
